What's New in Claude · Released 16 September 2026
No more choosing a mode. Hand it the task.
On 16 September 2026 Anthropic began merging Claude chat and Claude Cowork into a single experience. You ask for what you need, and Claude decides whether it is a quick answer or a task to work through: research, a report, a spreadsheet, a presentation, handed back as files you can edit. Everything Cowork could do is now available from any conversation.
It is rolling out gradually, starting with Pro and Max plans on web, desktop and mobile. Anthropic says Enterprise admins will hear at least 30 days before anything changes for their organization. For a company this is the biggest change of the quarter for people who do not write code, because the hardest part of Cowork was knowing it was there.

What the merged Claude does.
From Anthropic’s help center article, linked below.
- Whole tasks
- Describe the outcome and Claude works through the steps itself: searching the web, reading your files, running code, putting the results together. Several tasks can run at once.
- It keeps working when you leave
- Longer tasks run in the cloud with the laptop closed. Tasks that use files or apps on your computer need Claude Desktop open.
- Finished files
- Documents, spreadsheets with working formulas, and presentations you can open in PowerPoint.
- Your connected apps
- Apps such as Google Drive, Gmail, Microsoft 365 and Slack work while Claude carries out a task, so it pulls what it needs as it goes.
- Scheduled work
- Recurring tasks, such as a Monday summary of the inbox, can run in the cloud on a schedule.
- A permission setting
- Manual, the default, asks before each action. Auto keeps working without stopping and runs automated safety checks before acting. It applies to the whole conversation.
- One way only
- Chats, tasks, projects and settings carry over. Once an account has the new experience it cannot switch back to separate Chat and Cowork options.
What it means
how will claude cowork affect my business
What it means for your company.
In most firms we work in, a small group uses Cowork and everyone else uses Claude as a chat window. The merge removes the choice that split them. What it does not remove is the skill of handing off a whole piece of work, and that is the skill most people have never practised.
- Leadership
- The ceiling on what an ordinary user can delegate just rose. Whether your firm gets the value depends on whether people learn to ask for the finished report rather than the next paragraph.
- Your teams
- Work that took an afternoon of copying between tools, such as pulling last quarter’s board deck and summarising what changed, becomes one request with connected apps.
- Risk and compliance
- Auto mode and connected apps mean Claude acts with the access the person has. Decide where Auto is acceptable and where people stay on Manual, and write it on the one page your people actually read.
- Enterprise admins
- You get at least 30 days’ notice before the change reaches your organization. Use them: brief the teams and settle the permission rule before people find the new behaviour on their own.
This week
What to do this week.
Three things, in this order.
- Check who already has it
- On a Pro or Max plan, a message box that still shows Chat and Cowork means the account has not moved yet. Nothing needs to be switched on.
- Set the Auto rule
- One sentence on when Auto is allowed, for example: Auto for research and drafting, Manual for anything that sends a message or changes a shared file.
- Practise one real hand-off
- Pick a recurring report and have one person ask for the finished file, with the sources named. Compare it with how they did it last time.

Questions
The short answers.
The questions people ask about this release, answered in full.
What is the difference between Claude chat and Claude Cowork now?
In the new experience there is none. Anthropic merged them into one conversation from 16 September 2026, so Claude answers quick questions and takes on longer tasks in the same place without a mode to choose.
Which Claude plans get the merged experience?
It is rolling out gradually, starting with Pro and Max plans on web, desktop and mobile. More plans follow, and Anthropic says Enterprise admins will hear at least 30 days before anything changes for their organization.
Can Claude work while my laptop is closed?
Yes, for tasks that run in the cloud. Tasks that use files or apps on your own computer need Claude Desktop open.
Is Auto mode safe to use at work?
Auto keeps Claude working without asking before each step and runs automated safety checks before it acts. Anthropic advises staying close for work with real consequences, such as sending messages or changing important files. Set a firm-wide rule for where Auto is allowed.
